The respirator is NIOSH approved for use in temperatures to -25°F /
-32° C. For temperatures below +32° F / 0° C, approval requires use
of a Nose cup Assembly.
Respirators intended for routine use and respirators not routinely
used but kept for emergency use should be located in areas where
the temperature is maintained above freezing, +32°F / 0° C. Where it
is expected that the respirator will be used in ambient temperatures
near or below freezing, the respirator shall be equipped with a Nose
cup Assembly to reduce the formation of vision impairing mist or ice
on the interior of the facepiece vision area. Anti-Fog Applique is also
available to reduce facepiece fogging in conditions above freezing,
+32°F / 0° C. See ACCESSORIES.
If a respirator may be unavoidably kept at a temperature below freez-
ing before the next use, special care MUST be exercised to be certain
that all components of the respirator are THOROUGHLY DRIED after
cleaning and before storage.
If a respirator has been unavoidably kept at a temperature below
freezing and it is not possible to bring it to room temperature before
it is used, the following modification to the USE OF THE RESPIRA-
TOR section is required:
WHEN USING A NOSE CUP ASSEMBLY OR AN ANTI-FOG
APPLIQUE, do not exhale into the facepiece until the facepiece
is completely donned and the nose cup, if used, is properly in
place against the face.
noTe
EFFECTIVENESS OF ANTI-FOG APPLIQUE IN PREVENTING FOG-
GING OR MOISTURE CONDENSATION ON INTERIOR SURFACE OF
FACEPIECE ASSEMBLY MAY DIMINISH WITH REPEATED USES
OR OVER TIME. THE APPLIQUE CAN BE REPLACED IF IT HAS
DIMINISHED IN EFFECTIVENESS OR SUSTAINED SUBSTANTIAL
DAMAGE. SEE ACCESSORIES SECTION FOR REPLACEMENT KIT
INFORMATION.
Whenever use of the respirator is anticipated in areas at or below
freezing, the facepiece, regulator, airline connection hoses and air
supply hoses MUST be protected against exposure to water during
storage.
